By driving the drive device, each wind direction plate is rotated in the same direction and at the same angle.According to this method, since the wind direction of the wind direction plate is constant, It was not possible to obtain an appropriate wind direction depending on the situation and use. For this purpose, one of the wind direction plates is provided with an adjustment plate with a plurality of holes, and a connecting rod that transmits the rotational motion of the drive device as a reciprocating movement is optionally connected to the hole of this adjustment plate. has been provided to solve the above problem, but
According to this structure, when connecting the connecting rod to the hole in the adjustment plate, it is necessary to insert a finger between the wind direction plates each time to operate the connecting rod, which is very troublesome.

The present invention has been devised in view of the above points, and it is an object of the present invention to provide a wind direction adjusting device that can adjust the wind direction appropriately according to the situation and purpose of the room in which the equipment is placed by extremely simple operation.

An embodiment of the present invention shown in the drawings will be described below. Figure 1 shows the bottom plate and front frame of the indoor air outlet of an air conditioner omitted, and numeral 1 denotes a plurality of wind direction plates arranged in parallel at equal intervals on the frame, with protruding panels above and below the frame. The rotating shafts 1a of the wind deflecting plates 1 are rotatably supported on the same frame, and the lower rear end of each wind deflecting plate 1 is connected by an interlocking plate 2 in order to rotate and deflect the plurality of wind deflecting plates 1 at the same time. There is. Reference numeral 3 denotes an inwardly protruding attachment for connecting one of the wind direction plates 1 and the interlocking plate 2 to a second connecting rod, which will be described later, formed on the interlocking plate 2 as shown in the figure. One piece, the same mounting piece 3
A U-shaped engagement groove 31 extending in the front-rear direction is formed in. Reference numeral 4 denotes a low-speed electric motor as a driving device disposed at the bottom of the bottom plate of the main body air outlet 1, and its shaft 5 projects above the bottom plate and is shaped like a crank for rotational movement. Reference numeral 6 denotes a first connecting rod that converts the rotational motion of the shaft 5 into reciprocating motion, one end of which is pivotally attached to the tip of the coaxial shaft 5, and a connecting shaft 61 provided at the other end. A second connecting rod 7 transmits the reciprocating motion of the first connecting rod 6 as a left-right movement to the wind direction plate 1. The second connecting rod 7 is rotatably supported by a shaft 71 located approximately in the center of the second connecting rod 7. The first connecting rod 6 connects in the front-rear direction the center, right and left points of the ray with the coaxial 71 as the fulcrum.
elongated hole 8 for connecting the connecting shaft 61, for example, as shown in FIG.
A generally inverted dog-shaped elongated hole 8 connecting the two in the front and back direction is formed, and a connecting shaft 9 that engages with the engagement groove 31 of the mounting piece 3 is formed at the front end. Reference numeral 10 denotes a change plate disposed opposite the rear end of the second connecting rod 7, and a guide hole 11 extending in the left-right direction is formed in the plate surface.
For example, an arc-shaped guide hole 11 formed around the axis 71 of the second connecting rod 7 is provided, and the connecting shaft 61 of the first connecting rod 6 is inserted into the long hole 8 of the second connecting rod 7. and the change plate 1
0 is mounted on a rail 12 disposed on the bottom plate of the outlet so as to be opposite to each other and located in the front-rear direction, so that it can freely slide back and forth. Reference numeral 13 denotes an operating lever for operating the change plate 10, which has a substantially L-shape, for example, and has its bent portion rotatably supported by a shaft 14, and has one end of an operating rod 15 connected to its rear end; Further, the other end of the operating rod 15 is connected to the changing plate 10 through a slit formed in the outlet bottom plate.

The operation will be explained in the above configuration.
First, when the electric motor 4 is driven, the shaft 5 performs a rotational movement, and this rotational movement is converted into a reciprocating movement by the first connecting rod 6, and this reciprocating movement is further converted into a left-right movement by the second connecting rod 7. be done. At this time, the first
The connecting shaft 61 of the connecting rod 6 slides within the elongated hole 8 of the second connecting rod 7 and the guide hole 11 of the change plate 10.
This left-right movement is transmitted to each wind direction plate 1 through the interlocking plate 2, and each of the wind direction plates 1 automatically rotates in the same direction and by the same angle, and moves in the flow of cold air.

Here, for example, as shown in FIG.
When placed at the frontmost part 81 of the elongated hole 8, the wind direction plate 1
The swing direction is centered at the center, and cool air is blown uniformly into the room.

Next, as shown in FIG. 4, when the operating lever 13 is moved to the center and the connecting shaft 61 of the first connecting rod 6 is positioned in the bent part 82 of the long hole 8 of the second connecting rod 7, the wind direction plate 1 is the swing direction centered on the left side,
Furthermore, as shown in FIG. 5, when the operating lever 13 is moved to the left and the connecting shaft 61 of the first connecting rod 6 is positioned at the rearmost part 83 of the long hole 8 of the second connecting rod 7, the wind direction plate 1 is moved. The swing direction is centered on the right side.

In the above embodiment, three different wind direction states have been described, but by operating the operating lever 13, it is possible to obtain a wind direction depending on the situation and purpose of the room in which the equipment is placed.

Further, in the above embodiment, the wind direction plate 1 is attached to a frame provided in front of the main body outlet, but the wind direction plate 1 may be provided directly on the main body outlet.

Further, in the above embodiment, the long hole 8 of the second connecting rod 7 is formed in a substantially inverted dogleg shape, but it may also be in a generally doglegged shape as shown in FIG. 6, or as shown in FIG. The two elongated holes 8a and 8b, which connect points A, B, and C on the left and right rays and one point a, b, and c in the front-back direction, are slightly shifted in the front-back direction. The swing angle of the wind direction plate 1 may be adjusted by selecting the two elongated holes 8a and 8b in advance when installing the main body.However, in this case, the operation of the operating lever 13 and the wind direction may be adjusted. Since the swing direction of board 1 is reversed, the display board should be changed at the time of selection. In addition, as shown in the same figure, the elongated hole 8
The operating lever 13 is formed with a convex portion that protrudes inwardly.
Alternatively, the operation may be performed reliably.

Further, in the above embodiment, the U-shaped engagement groove 31 is formed in the mounting piece 3, and the connecting shaft 9 is formed in the front end of the second connecting rod 7, but the present invention is not limited to this. Instead, for example, a connecting shaft may be formed on the mounting piece 3, and a U-shaped engagement groove that engages with this connecting shaft may be formed at the front end of the second connecting rod 7; Although the mounting piece 3 is integrally formed on the interlocking plate 2, the present invention can also be achieved by forming the mounting piece 3 protruding inward on one of the plurality of wind direction plates 1. Initial objectives can be achieved.

As described above, in the present invention, the change plate is slid back and forth by operating the operating lever, and the connecting shaft 61 of the first connecting rod 6 is moved to an arbitrary position in the substantially dogleg-shaped long hole of the second connecting rod. Since the device adjusts the wind direction of the wind direction plate by moving it, it is possible to arrange the equipment without having to perform the extremely troublesome operation of inserting your finger between the wind direction plates as in the past. The airflow direction can be adjusted appropriately depending on the situation and purpose of the room with extremely simple operations.
